I think it might be better (cheaper/easier) to use a non pressurized tank with a pressurized copper coil heat exchanger inside. You could use a stainless steel 55 gallon drum for this, or probably some other containers that aren't rated for pressure. I don't think a clean used stainless steel drum is all that expensive. If you pass your cold water through a short coil of copper tubing in a drum full of hot water, it will get hot pretty quickly. You could use more than one drum to increase your capacity.

You might even be able to use one of those 275 gallon IBC totes the same way, depending on how hot your water temperature is. They are safe to at least 120 degrees, if not more.
